slothful

This term carries a heavy moral or judgmental weight, often associating laziness with a character flaw or a spiritual failing. It suggests a deep-seated aversion to exertion that goes beyond simple tiredness, implying a state of chronic inertia or a willful refusal to engage with responsibilities.

When applied to processes or systems, it describes a sluggishness that is frustrating or obstructive. It evokes an image of heavy, dragging movement, making it more evocative and critical than the neutral word slow.
